As said in the additional information, these are websites which people claim are unblocked to schools. Some of them are even "unblockable"!! which is pretty amazing...although, don't get your hopes up because it really just depends on the school domain. But anyhoo, hope this works for you! Only bit of advice I'd say is...if you're at school, make sure you turn your monitor slightly so the teacher can't see it so well. Or another trick is have another tab open (have it on Google or some other casual website which you're allowed to go on) and when the teacher comes round, switch to that tab and then minimize the browser so if the teacher looks at the wee thing at the bottom of the screen, it will say "Google" and none of the other tabs =DHappy playing games, wasting time and not doing work when you're meant to!
